Climate change is creating more than higher temperatures. Rising sea levels could mean that, by the year 2100, many ocean-side homes — and their homeowners — could be underwater, literally. Specifically, approximately 1.9 million U.S. homes, approximately 2% of the current stock worth $882 billion, could be swallowed up, according to Zillow.

The real estate company based its conclusions on a study published in Nature Journal, which suggested that sea levels could increase by about six feet by the end of the century, assuming continuation of the current greenhouse gas emissions. At that level, approximately 300 U.S. cities are expected to lose at least half their homes, with 36 cities gone completely.
